WitrynaThe cell cycle is made up of two main stages: interphase and mitosis. During interphase, cells are duplicating their material and synthesising proteins to prepare to divide. Interphase encompasses 3 phases: G1, S and G2. During S phase, DNA is replicated. Mitosis encompasses prophase, prometaphase, metaphase, anaphase telophase.

G2 phase, Gap 2 phase, or Growth 2 phase, is the third subphase of interphase in the cell cycle directly preceding mitosis. It follows the successful completion of S phase, during which the cell’s DNA is replicated. G2 phase ends with the onset of prophase, the first phase of mitosis in which the cell’s chromatin condenses into chromosomes.
